The vision may be briefly disposed of. Its original is the great lamp which stood in the tabernacle, and was replaced in the Solomonic Temple by ten smaller ones. These had been carried away at the Captivity, and we do not read of their restoration. But the main thing to note is the differences between this lamp and the one in the tabernacle. The description here confines itself to these: They are three--the 'bowl' or reservoir above the lamp, the pipes from it to the seven lights, and the two olive-trees which stood on either side of the lamp and replenished from their branches the supply in the reservoir. The tabernacle lamp had no reservoir, and consequently no pipes, but was fed with oil by the priests. The meaning of the variations, then, is plain. They were intended to express the fuller and more immediately divine supply of oil. If the Revised Version's rendering of the somewhat doubtful numerals in verse 2 be accepted, each several light had seven pipes, thus expressing the perfection of its supplies. Now, there can be no doubt about the symbolism of the tabernacle lamp. It represented the true office of Israel, as it rayed out its beams into the darkness of the desert. It meant the same thing as Christ's words, 'Ye are the light of the world,' and as the vision of the seven golden candlesticks, in Revelation i. 12, 13, 20. The substitution of separate lamps for one with seven lights may teach the difference between the mere formal unity of the people of God in the Old Testament and the true oneness, conjoined with diversity, in the New Testament Church, which is one because Christ walks in the midst. Zechariah's lamp, then, called to the minds of the little band of restored exiles their high vocation, and the changed arrangements for the supply of that oil, which is the standing emblem for divine communications fitting for service, or, to keep to the metaphor, fitting to shine, signified the abundance of these. The explanation of the vision is introduced, as at Zechariah i. 9, 19, by the Prophet's question of its meaning. His angelic teacher is astonished at his dullness, as indeed heavenly eyes must often be at ours, and asks if he does not know so familiar an object. The Prophet's 'No, my Lord,' brings full explanation. Ingenuously acknowledged ignorance never asks Heaven for enlightenment in vain.
